HERBERT CLINTON SOULE, OF WILKINSBURG, PENNSYLVANIA, ASSIGNOR TO WEST-INGHOUSE ELECTRIC AND MANUFACTURING COMPANY, A CORPORATION OF PENN-SYLVANIA.

Application filed November 8, 1909.

To all whom it may concern Be it known that I, HERBERT CLINTON Scum, acitizen of the United States, and a resident of Vilkinsburg, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Stationary Inductive Apparatus, of which thefollowing is a specification.

My invention relates to stationary inductive electrical apparatus and ithas special reference to such apparatus as is cooled by a circulation ofair.

The object of my invention is to provide a simple air-blast transformerstructure with which a reactance coil. may be mechanically combined,whereby the combination may occupy a minimum amount of floor space andthe cooling of the reactance coil may be independent of the cooling ofthe transformer.

Reactance coils have frequently been associated electrically withtransformers and with other electrical apparatus, but no provision hasusually been made for cooling them and they have usually beenmechanically independent of the transformer.

According to my present invention, I dispose a reactance coil in the airpassageway through which the air-blast transformer, with which it isassociated, is supplied with cool air, the coil being secured directlyto the transformer casing, so that the two devices may be handled.together, and a hood or deflector being provided for deflecting apredetermined amount of the cool air through the reactance coil.

Figure 1 of the accompanying drawings is a partially sectional elevationof a trans former and a reactance coil combined in accordance with myinvention. Figs. 2 and 3, are, respectively, a plan view and a sectionalelevation of the hood or deflector with which the reactance coil of Fig.l is provided. Fig. 4 is a sectional elevation of a transformer station,showing the usual provisions for forced ventilation.

Referring to Figs. 1, 2 and 3 of the drawings, the structure here showncomprises a transformer 1 disposed in a housing 2, which is mounted onany suitable base 3, and a reactance coil 4, which is secured to thebottom of the casing 2 and is disposed in a passageway 5 in the base 3.The bottom of the housing is open to admit cool air from below and itstop is provided With a lid or damper Specification of Letters Patent.

6 which is pivotally secured to a cover member 7 of the housing and hasan adjusting lever S, a guide 9 being provided in order that the dampermay be locked in any position to which it may be adjusted. The reactancecoil may be of any well-known structure comprising, as shown, alaminated core 10, end frames 11, tie-bolts 12 and coils 13. Thereactance coil is secured to the casing 2 by means of strips lt whichare bolted, at their ends, to inwardly extending flanges 16 or aresecured to the bottom of the housing by any suitable means, and whichare bent to form a cradle for the coil. The coil is provided with a hood17, which is clamped to one end of the frames 11 and is provided with afine projection 18 which terminates in a manhole or removable panel 18in the wall of the housing 2. The panel 18- is provided with an opening19, having a flange 20 to receive the end of the flue, and a lid ordamper 21 by which the area of the flue out let may be adjusted.

The operation of the combined transformer and reactance coil may be bestunderstood by reference to Fig. 4, in which a battery of transformers isshown mounted directly on the floor 22 of a transformer station,communication being established from a chamber 23 below the floor to thetransformer housings through the openings 5. The chamber 23 is suppliedwith cool air by means of a blower 24, which is driven by an electricmotor 25 or by any other suitable means, and the intake 26 of whichcommunicates with the outside atmosphere. \Vhen the motor 25 isoperated, the cool air is drawn through the intake 26 and is forced intothe chamber 23, in which a slight air pressure is maintained. The amountof cool air which passes through the transformers is dependent upon thepositions to which the dampers 6 are adjusted, and the amount of airwhich passes through the reactance coils depends upon the adjustment ofthe dampers 21. By this means, the reactance coil may be more cheaplyconstructed and more economically designed, since its core and windingsare thoroughly ventilated, and a separate casing and expensivemechanical parts are unnecessary. Not only is the floor space occupiedby the set, no greater than ordinarily occupied by the transformeralone, but, furthermore, the circuit connections are materiallysimplified, a short rigid conductor being located Within the transformerhousing for connecting the two devices together and only one pair'ofleads being necessary.

The type of transformer which is illustrated forms no part of my presentinvention, and those skilled in the art Will readily understand that myinvention may be applied to various other combinations of electricalapparatus.

I claim as my invention:

l. The combination with a main electrical apparatus, and a containingcasing therefor, of an auxiliary apparatus disposed in the path of newof the cooling fluid supplied to said main apparatus and suspended fromthe main casing, a hood secured to the auxiliary apparatus and providedWith a flue which may communicate With the outer air, and means toregulate the flow of fluid through said flue.

2. The combination with a main electrical apparatus and a containingcasing therefor, of an auxiliary apparatus disposed in the path ofcooling fluid supplied to said main apparatus and supported by the maincasing, a hood secured to the top of the auxiliary apparatus andprovided With a flue which communicates With the outer air, and means toregulate the flow of fluid through said flue and through said mainelectrical apparatus.

3. The combination With an air-blast transformer,'and a casing thereforhaving an adjustable lid or damper, of a reactance coil suspended fromthe casing, and positioned in the path of flow of the cooling airWhichissupplied to said air blast transformer and a hood or deflectorfor the reactance coilhaving an independent damper by which the amountof cool air passing through" the reactance coil may be regulated.

In testimony whereof, I have hereunto subscribed my name this 29th dayof Oct,

HERBERT CLINTON SOULE.
